ok i have a charger and its telling ‘low tire pressure‘does any one know how much the tires should be?
Assuming its a modern Charger (as it has a low preesure indicator) 30 psi - from the inside driver door.
The max load part at a pressure is just that, the extreme. The owner's manual should have the information for a standard tire for the vehicle. Most passenger cars recommend something in the 35 p.s.i. range. If you have a truck with truck tires, it will be more. I had LT-class tires on a pick-up and the maker recommended 55 for normal use with my weight class of truck. M.G.W. or maximum Gross Weight affects the number, too. The heavier the total weight, the greater the pressure.
The factory recommended tire pressure is on a sticker inside the drivers door. If It's missing it will be in the manual in the glove compartment. If the tires seem too soft to you as you drive read the tire pressure printed on the sidewall of the tire. That's the tire manufacturer's maximum recommended pressure. Inflate to within four pounds of the sidewall pressure when the tires are stone cold. There's a little trick out today to help maintain tire pressure to keep the low tire pressure gage happy: Go to a tire shop and have the air in the tires bled off, purged and inflated with nitrogen. The molecules of the inert gas - nitrogen are enormous and less apt to leak from the tire beads and valve stems. There's no moisture or dirt in nitrogen so the inside of the wheels don't rust or corrode. It's also been proved that tire tread life will be extended by 15 - 20%. The tires will not build as much pressure when hot or lose it when cold.
